Toilet seat with built-in lift apparatus

ABSTRACT

Toilet seat with built-in lift apparatus comprises a toilet seat that has built-in long pivot-rod whose each end has installed a small gear, a U-shaped lever whose each end has installed a large gear each and a reverse U-shaped plate fastener that has two side-wings. The U-shaped lever is fastened onto side-wings of U-shaped plate fastener. The toilet seat and the plate fastener are fastened onto toilet with a pair of bolts. Both small gears and large gears catch snugly each other. When large gears rotate clockwise small gears rotate counter clockwise and vice versa. Man steps downward the U-shaped lever to lift toilet seat and releases slowly U-shaped lever to lower toilet seat.

THE BACKGROUND OF THE INVENTION

Man has to lift toilet seat with hand before urination to prevent toilet seat from wet. The present invented toilet seat with a built-in lift apparatus allows man to step on it to lift toilet seat with foot instead of hand. Man also can releases it slowly to lower the toilet seat.

BRIEF DESCRIPTION OF THE INVENTION

Toilet seat with built-in lift apparatus comprises a toilet seat, two sets of built-in gears and an U-shaped lever. Its toilet seat can be raised by stepping downward the U-shaped lever. And toilet seat can be lowered by releasing stepping slowly.

THE DETAILED DESCRIPTION OF THE INVENTION

Referring now in detail to the drawings numeral 10 is a toilet seat with built-in lift apparatus. Numeral 11 of FIGS. 1, 2, 3, 4 and 5 is a toilet seat. Numeral 12 of FIGS. 1, 2 and 5 is a built-in pivot rod of toilet seat 11. Numeral 13 of FIGS. 1, 2, 3 4 and 5 is built-in small gear of toilet seat and is installed at both ends of pivot rod 12. Numeral 14 of FIGS. 1, 2 and 5 is ring-bolt that hooks pivot rod 12. Numeral 16 of FIGS. 1, 2 and 5 is bolt-nut that screws onto ring-bolt 14 to fasten toilet seat 11 to toilet 15 as illustrated in FIGS. 3 and 4. Ring-bolt 14 fastens toilet seat 11 onto toilet 15 as illustrated in FIGS. 3 and 4. Numeral 17 of FIGS. 1, 2, 3 and 4 is a U-shaped gear-lever that has installed a large gear 18 of FIGS. 1, 2, 3 and 4 at both ends 20. Large gear 18 of FIG. 2 has a pivot bolt 21 at inner center. Numeral 19 0f FIGS. 3 and 4 is water tank. Numeral 22 of FIG. 2 is nut that screws onto pivot bolt 21 to fasten U-shaped gear-lever 17 to the reverse U-shaped plate fastener 23 of FIG. 1, 2, 3, 4 and 5. Numeral 23 of FIGS. 1, 2, 3, 4 and 5 is reverse U-shaped plate fastener that has a top plate 24 and two side-wings 25. Top plate 24 of FIGS. 1, 2 and 5 has two holes 27 to allow ring-bolt 14 to pass to fasten it onto toilet 15 with bolt-nut 16. Toilet seat with built-in lift apparatus 10 is fastened onto toilet 15 by ring-bolt 14 and bolt-nut 16. Each side-wing 25 of FIGS. 2 and 5 has a hole 26 to allow pivot-bolt 21 to pass. After pivot-bolt 21 passes through hole 27 of side-wing 25 from outside in nut 22 screws onto pivot-bolt 21 to fasten U-shaped gear-lever 17 onto reverse U-shaped fastener 23. The small gear 13 of pivot-rod 12 catches snugly large gear 18 of U-shaped gear-lever 17. Large gear 18 is preferably twice as large as small gear 13, therefore when large gear 18 turns 30 degrees small gear 13 will turn 60 degrees to lift toilet seat 60 degrees open. User steps U-shaped gear-lever 17 downward to lift toilet seat and releases slowly U-shaped gear-lever 17 to lower toilet seat. 

1. Toilet seat with built-in lift apparatus comprising a toilet seat, a pair of small gears, a pair of large gears, a reverse U-shaped plate fastener, two bolt fasteners and a U-shaped gear-lever.
 2. The said toilet seat in claim 1 has a built-in long rod as pivot that is installed at the rear end and the said a pair of small gears in claim 1 that each gear is installed at the end of the said built-in long rod. Wherein the said built-in long rod is as long as the top of toilet where the pivot of toilet seat is located and is fastened onto toilet by bolt-fastener.
 3. The said reverse U-shaped plate fastener in claim 1 is a U-shaped plate that is placed on top of toilet under the said built-in long rod in claim 2 and has a top plate and two side-wings. Wherein the said top plate is as long as the said built-in rod in claims 2 and 3 and has two holes in the middle to pass the said two bolt-fasteners in claim 1 that hooks the said built-in long rod in claims 2 and
 3. Wherein the said two side-wings each has a central hole to catch the said U-shaped gear-lever in claim
 1. 4. The said U-shaped gear-lever in claims 1 and 3 is a U-shaped lever whose each end has installed one of the said a pair of large gears in claim
 1. Wherein the said large gear each has a bolt installed at the center of inner side to pass through the said central hole of side-wings in claim 3 and has a nut to screw onto it. Wherein the said large gears is preferably twice as large as the said small gears in claims 1 and
 2. 5. The said a pair of small gears in claims 1, 2 and 4 catch snugly the said a pair of large gears in claims 1 and 5 and rotate in reverse direction to the said a pair of large gears.
